A AUTOMOBILE-HEATER.

Specification of Letters Patent.

Patented Jan. 11 2, 11915.

Application filed October 17, 1913. Serial No. 795,628.

To all whom it mag concern:

Be it known thatLCHARLEs It. FAnUoLo, a citizen of the United States,and a resident of the borough of Bronx, in the city, county, and Stateof New York, have invented certain new and useful Improvements inAutomobile-Heaters, of which the following is a specification.

This invention relates to the heating of automobiles.

My objects have been to provide a thoroughly practical and efiicientmeans for heating the interiors of such vehicles by use of the enginecooling water, to make the construction simple and ineXpensive, compactand conformable, to keep down the added weight, to enable the inventionto be installed neatly and conveniently in existing machines or embodiedtherein with advantageat the time of manufacture, and to provide aheating attachment of such character as to be readily adaptable todifferentconditions encountered in automobiles of various kinds. Theseand other advantages, which will be apparent to those skilled in theart, are attained by the novel features ofconstructionsand combinationsof parts hereinafter described and claimed.

' An illustrative embodiment of the invention is shown in theaccompanying drawings wherein:

Figure 1 is a side elevation showing the invention installed, the P r ofthe which being represented somewhat conventionally and in the main bybroken lines; 2 is a plan view of the heating radiator, lts case beingpartly broken away; Fig. 3 1s a section on the line 83 of Fig. 2; Fig.4: 1s a section on-the line H of Fig. 2; Fig. 5 is a detail enlargedview showing a part of the connections; nig. 6 is a vertical sectionthrough the corresponding part of Fig. 5; Fig. 7 is a detail of apart'shownin Figs. 5 and 6; and l ig. 8 isa detail illustrating thenature of the flexible pipe lines employed.

The drawing indicates a vehicle with a limousine body; but it will beunderstood that the invention is applicable to any type of car, open orclosed. particularly for heating the compartment or compartmentspertaining to the rear seat or seats, which do not receive the benefitof the heat radiated by the engine. The latter is indicated in aconventional way at 10,

- of the box It is designed more beneath the usual hood; The "engine hasthe usual spaces for circulation of cooling water, hereinafter termedthe water-jacket, and at the front of the hood is a usual or suitableform of radiator 11, through Which the hot water from the water-jacketpasses to dissipate its heat into the atmosphere,

thence returning to the water-jacket again. The outlets from the.water-jackets of the several cylinders are connected to a dischargemanifold 12, and similarly their inlets are in communication with areturn manifold 13. The discharge and return connections are tapped intothe upper and lower portions of the radiator, and include flexible orhose sections 14, 15, by means of which injury to the joints byvibration is avoided. A pump 16 is interposed in the return connectionand serves to maintain a circulation through the engine cooling systemand also through the vehicle heating system.

The heating radiator is represented at 17,

and is shown placed on the floor immediately in front of the rear seat.It is preferably constructed of a suitable number of parallel lengths ofpipe connected by return bends; andthe whole is preferably inclosed in aflat perforated metal caseor box 18, the side and front edges of whichare desirably beveled, as indicated at 19, to present a neat finish andavoid danger of the occupants tripping. The inlet and outlet of theradiator are preferably, though not necessarily, located at the sameend, and as shown the inlet 20 passes through the front whilethe outlet21 drops down} ward through the bottom thereof. Obviously the detailsmay be varied. The supply and return lines 22, 23 leading to said inletand outlet, respectively, are connected with the hot and cold sides ofthe cooling system, by being tapped into the flex ble hose sections 14,15, and are light, flexible and anti-vibrating in character. To this endT construct them of spirally wound flexible metal tubing having at therear ends suitable connections with the inlet. and outlet of theradiator, and at their forward ends being provided with fittings 24, 25for con- This con-,

. single angular member,

manner preferred or that may be rendered desirable by the enginepresence of other parts or accessories, while merely by varying thelength of the flexible pipes water-tight, and, in the case of the supplyline, being of further advantage in heat. As indicated, the tubing maybe inclosed,- where desired, in a cover or envelop 27, which preferablyhas ,an asbestos packing 27' in the case of the supply line. Assuggested in Fig. 8, the asbestos lining is desirably formed byemploying a strip of asbestos of substantially:

the same-width as the metal strip and winding it simultaneouslytherewith.

A suitable and preferred construction of the fittings 24:, 25 isillustrated moreparticularly in Fig. 5. As here shown a flanged endpiece 28 is soldered or otherwise secured to the end of the flexiblepipe, a flanged nipple 29 is passed through an opening formed for thepurpose in the wall of the hose section 14, and a union 30 draws the twotogether. The nipple 29 is held in place with a tight joint by a nut 31screwed onto the nipple, a washer 32 being inter- A. washer or part 33having a similar function is interposed between the flange of the nipple29 and the wall of thehose on. the inside, and as shown in. Fig. 6 ispreferably curved transversely to conform to the curvature of the said.wall. This member may be made of suitable extent and serves toreinforce the.

hose at the junction of the supply line therewith. Tt will be understoodthat the fitting or coupling 15 is of simi ar character, and that thedetails of construction may be varied in-both instances.

Means are provided inside the discharge connection section 14 forcausing a proper proportion of the hot water to flow into the inlet ofthe supply connection. To this end a member 34 is disposedacross theinterior of this hose section, the same being provided with an aperture35 of suitable dimensions. Thus the passageway to the engine radiator isrestricted at a point beyond the inlet of the supply line, so th'ataportion of the flow As shown the parts 33, 34. are advantageously formedas a the passage-restricting member being thus anchored in place withoutthe n eces'sity for special means for or car design or the a parts whereleakage might bestos lining 26, the latter rendering the or vehicle.

'cut off the radiator 17, the vent is opened permit maaeoe the purpose.It will be understood that the passage-restricting means need not bevemployed in the hose section 15. y

The supply line 22 may be provided with a flexible branch 36, which isconnected in a suitable manner with anoutlet opening 37 near the top of.the engine radiator, but preferably below the inlet opening 38. Thisbranch connection may, however, be omitted,

or in some instances, for example with the so-called siphon .enginecooling system, it couldbe employed alone, without the connection withthe hose section 14. When employed in conjunction with the otherconnec-- tion it insures an adequate supply of water to the heatingradiator in the car without the necessity of very materially reducingthe area of the connection 22.

Aswill be apparent, the heater may be applied with a minimum of laborand without any substantial alteration in the engine When in use part ofthe water passing from the engine water-jacket to the cooling radiatorenters the supply line 22 and proceeds to and through the heatingradiator, whence it passes through the re turn line 23 to the hosesection 15, and, havhot ing given up its heat in the interior of thecar, reunites with'the cool water returning from the cooling radiator.Both then enter the intake of the pum and are forced again -through thecooling spaces of the engine.

Thetwo radiators are, stantially in parallel.

thus, connected sub- The cooling radiator always remains in ply andreturnlines neartheir forward ends.

Couplings ll, 42 enable the major portions of these lines to bedisconnected from the valve fittings when it is desired to remove theattachment from the vehicle. At such time the valves are, of course,

closed. The valve of the fitting 40 inthe return line is preferably adrain cock, as indicated. When this valve is open for throughcommunication the drain is closed. but when closed to v.

to the draining ofithe radiator. .This valwe also enables air; to bevented in event of the radiator it? becoming air-bound. The dispositionef'the supply and return lines is preferably 'suchlthat the supply lineis higher than the return, and the latter is pireferably arranged with acontinuous pitch valve fitting 40. The radiator is alsopreferablvarranged on a slight slant asindicated.

While I have described the illustratedemhe outlet of the radiator 17to-the bodiment of the invention vwithparticularity so that the same maybe fully understood. it

will be apparent that l amznotjnecess'arilylimited to the detailsshowmand thatnumerous changes, omissions and substitutiens'may be madewithout departing from the invention.

WhatI claim as new is:

1. In an automobile, the combination with the; engine thereof providedwith a waterjacket, a cooling radiator, and removable *fleXible hosesections connecting the engine water-j acket with the cooling radiatorat top and bottom, of a heater within the car, and flexible. supply andreturn lines leading to and from said heater and connected,respectively, to said hose sections.
